SAFETY RAZOR.

Application filed December 2', 1922.

rfhis invention relates to safety razors.

One object thereof is to provide a device of the character describedhaving means whereby both the cutting edges of the safety razor blademay be sharpened on a strop with the various parts of the deviceremaining in the position assumed by them when the safety razor is usedin shaving, so that the razor blade may be readily stropped withoutnecessitating the readjustment or removal of parts, merely bypositioning the strop in operative relation to the blade.

Another object is to provide a device of the character described havingsimple means for reversibly holding the safety razor blade so that thelatter may be easily reversed so as to present rst one and then theother cutting edoe, and which means shall also permit the blade to bereadily secured in position on the blade holder and removed therefrom asdesired.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

Certain features herein shown and described are shown, described andclaimed in my cro-pending application Serial No. 595,- 088 filed in theUnited States Patent `Office on the 19th day of October, 1922, andaccordingly not claimed herein.

`With the above exception the invention accordingly consists in thefeatures of construct-ion, combinations of elements and arrangement ofparts which will be exemplified in the construct-ion hereinafterdescribed and of which the scope of application will be indicated in thefollowing claim.

In thc accompanying drawing, in which is shown one of various possibleillustrative embodiments of this invention,

Fig. 1 is an end elevational View of a safety razor embodying myinvention, with a razor strop positioned thereon shown in dotted lines,the razor handle being broken away to conserve space;

Fig. 2 is a plan view corresponding to Fig. 1;

Fig. is a sectional view cut along line 3`3 of Fig. 1;

F f1 is a sectional view through the blade holder bar cut along line4.--4 of Fig. 2; and

Fig. 5 is a plan view of the razor blade preferably employed with myinvention.

Referring in detail to the drawing, indicates a handle member secured toa frame Serial No. 604,537.

11 on which the various parts of the safety razor are mount-ed. Theframe 11 is provided at the front and rear ends thereof with upstandingv bearing members 12, 12 in which are journaled a pair of rollers 13, 13in vertical alignment and spaced from each other. At one end of theupper roller 13 is mounted a gear leladapted to mesh with the gear 15 atthe corresponding end of the roller 15. A. pair of guide rollers 16, lo"are journaled to either side of and below the roller 13 for the razorstrop 17 which when the blade is to be sharpened passes over theserollers 16, 18 and beneath the roller 13 as shown in Fig. 1.

Extending from the upper ends of the frame 12 is a pair of end pieces orconnecting bars`12?, 12b, each secured at one end to the correspondingend of the roller 13 so as to be movable therewith and receiving betweenits freeends the blade holder. The latter comprises a cross bar 18pivotally held between the connecting block 12a, 12b by means oftrunnions 18', 18h journaled in the free ends of said connecting blocks.The material of the cross bar is punched out adjacent the ends thereofto provide raised tongues 18c adapted to engage in correspondingelongated slots 19C in the safety razor lade 19. A central opening 19dis further provided in the blade 19 to receive a central raised portion18l formed in the cross bar 18. ln inserting the razor blade in theholder, one of the tongues 18c is disposed in engaging position over thecorresponding opening 19 and the safety razor blade slid thereunderuntil the other prong engages in the other opening. The central raisedportion 18d then registers in the opening 191 in the blade and acts as astop to prevent movement of the blade relative to the cross bar.Adjacent the trunnion 18' is a rectangular hub 18C adapted to rest in arectangular slot l8r formed in the corresponding connecting block 12a.The opposite block 12bis provided with a spring 20 which acts againstthe trunnion 181 so as to normally keep the rectangular hub 18c of theopposite trunnion 18FL in the rectangular slot 18f. When it is desiredto reverse the blade the cross bar 18 is pushed forward so that thetrunnion 18D will act against the spring 20 and the hub 18e in this waymoved out of the rectangular slot 181. The trunnion 18:L will then beloose in said slot, thus permitting the rotation of the cross bar.

lOO

A guard 2l is provided for the razor blade comprising a horizontalsupporting member l slidable in the guide 22'v secured at the top of thehandle l0. Extending from tl e support 2l is a thumb piece 2,1." for. inanipulating the guard. A pin 23 'extends `from the member 2 n into thehandle in cooperative relation to a spring` member 2li secured therein.The guard portion is shown at and has at either end thereof` upturnedengaging lips 25u, 25 adapted to receive the endsot the blade 19.siivill be readily understood, the spring 24 acts against the pin 23 soasto normally urge the lips 25,` 25" against the, razor blad@ lWhen itis desired to free the razor blade, the thumb piece 2lb is pushed inwardagainst the action of the spring 23, thus moving the guard away fromtheblade until the lips 25225 are out of Vengagement therewith. l f` i'ln stropping the blade, the strop 17 is passed over the guide roller 16underneath the gear Wheel 13 over the'other roller 16, and underneaththe razor blade and above the guard'member.. is the handle 10l ismovedback andforth, the blade holder including the coi'inecting blocks1Q, l2", the cross bar 18, and the blade thereon is given a rockingmovement bythe operation oi' the gears`18., 18, thus presenting lirstone and then the other side of one razor edge.

The other razor edgeA is then sharpened by reversing the cross bar 18 inthe manner alreaclyy described.

it will thus be seen that there is provided a device in which theseveral objects of: this invention are achieved and which i.; Welladapted to meet the conditions of practical use.

As various possible embodiments might be mad-eoili the above inventionand as various changes n'iight be made in the emb,odi ment aboveset'torth, it is to, be understood that all'matter herein set forth orshown in the aecoinpanying drawings is to be interpreted as illustrativeand notl in a limiting sense.

Having thus described my invention l claim as iiewiand desire to secureby Letters Patenti-V device of the character described comerising ahandle member, av supporting iframe seeured thereto including connectingbifirs'pivoted to said trame, a double edge razor blade, a holderrel-easably secured to the blade bet-Ween the cutting edges thereof, andrevoluvbly mounted on said bars to selectivelyhold either edge of theblade in effective position, a spring pressed memA her disposed inoperative relation to said holder.

"n testimony whereof I ailix my signature.
